A charging system of a vehicle includes a first conversion device of a first drive system of the vehicle, the first conversion device connected to a first electric motor. The system also includes a second conversion device of a second drive system of the vehicle, the second conversion device connected to a second electric motor. The first drive system and the second drive system are connected to a battery system of the vehicle. The system also includes a switching assembly including a plurality of switches configured to selectively connect the first electric motor and/or the second electric motor to a charge port of the vehicle, and a controller configured to control the switching assembly to define a conversion circuit that includes components of the first drive system and/or the second drive system, and control the conversion circuit to regulate an output voltage and supply power to an energy storage system.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The charging system of claim 1, wherein the energy storage system includes a battery of a second vehicle.
3. The charging system of claim 1, wherein the first inverter and the second inverter are connected in parallel across the propulsion bus.
4. The charging system of claim 3, wherein the first conversion device is a first inverter and the second conversion device is a second inverter.
6. The charging system of claim 1, wherein the controller is configured to simultaneously form the boost converter circuit and the buck converter circuit to increase or decrease a received voltage.
7. The charging system of claim 1, wherein one of the first conversion device and the second conversion device is operated in a pass-through mode while another of the first conversion device and the second conversion device is operated to form the buck converter circuit or the boost converter circuit.
8. The charging system of claim 1, wherein the first conversion device is a first inverter and the second conversion device is a second inverter, and wherein the switching assembly includes a first switch configured to selectively connect a phase of the first motor and the first inverter to the charge port, and a second switch configured to selectively connect a phase of the second motor and the second inverter to the charge port.
9. The charging system of claim 8, wherein the first switch is connected to a neutral point of the first motor, and the second switch is connected to a neutral point of the second motor.
11. The method of claim 10, wherein the energy storage system includes a battery of a second vehicle.
12. The method of claim 10, wherein the first conversion device is a first inverter and the second conversion device is a second inverter.
14. The method of claim 10, wherein forming the conversion circuit includes simultaneously forming the boost converter circuit and the buck converter circuit to increase or decrease a received voltage.
15. The method of claim 10, wherein one of the first conversion device and the second conversion device is operated in a pass-through mode while another of the first conversion device and the second conversion device is operated to form the buck converter circuit or the boost converter circuit.
17. The vehicle system of claim 16, wherein the first inverter and the second inverter are connected in parallel across the propulsion bus.
19. The vehicle system of claim 16, wherein forming the conversion circuit includes simultaneously forming the boost converter circuit and the buck converter circuit to increase or decrease a received voltage.
20. The vehicle system of claim 16, wherein the first conversion device is a first inverter and the second conversion device is a second inverter.
